DRAWING-ROLL CLEANER FOR SPINNING-FRAMES.

Specification of Letters Patent.

Patented March 24, 1908.

Application filed. April 19, 1907. Serial No. 369,129.

To all whom it may concern:

Be it known that JAMES S. DEELEY, deceased, late a citizen of the United States, and'residing in Bellingham, in the county of Norfolk and State of Massachusetts, and WILLIAM W. OLLENDORFF, a citizen of the United States, residing at West Medway, in said county and State, have invented certain new and useful Improvements in Drawing-Roll Cleaners for Spinning-Frames, of which the following is a specification, reference being had therein to the accompanying drawings, which form a part thereof.

The invention relates to drawing roll cleaners for spinning frames and more particularly to that type thereof adapted to be applied to the assembled machine, and to traverse the top roll from end to end by means whereby it is self-propelled.

The main object of the invention is to provide a compact cleaning device which may be applied to the top drawing roll and brought into and maintained in an operative relation thereto, by gravity solely.

A further object is to provide a device of this character wherein the cleaner will subject the roller to the action of an extended surface of abrasive material in a manner to remove all dust, dirt, and sliver therefrom and such further novel features of construction and combination of parts as are hereinby a progressive movement thereof from en to end of said roll.

A still further object is to provide a device of this character wherein the cleaner will not only remove all dust, dirt, and sliver from the roll, but will also accumulate and take perspective view of the drawing rolls of a up the same in a manner to prevent the fouling of the portions of the machine under said roll.

A still further object is to provide a device of this character embodyingtherein a plurality of propelling cones, so spaced apart as to preserve the equilibrium of the entire device, and means whereby the axes of said cones may be laterally adjusted to bring their inner surfaces into substantial alinement with each other and with'the drawing roll.

A still further object istoprovide a device of this character wherein the axes of the cones may be so adjusted as to permit the application of the device to different machines, and as to regulate the extent of the superficial contact between each such cone and the drawing roll to govern the friction therebetween, and to insure that degree of friction necessary to. attain the desired feeding movement of the device.

A still further object is to provide a device of this character wherein the propeller cones will act not only to drive the device, but also as means aiding in maintaining it upon the roller in conjunction with one or more neutral stops, adapted to pass over theopposite side of the roller, the abrasive material being positioned above, and between, such cones, and said stops. And a still further object is to provide a device of this character which will be composed of few parts so constructed and arranged as to effectively maintain the device on the roller, clean the roller, and propel the cleaner from one end thereof by a gradual feeding movement.

The invention consists primarily in a drawing roll cleaner for spinning frames comprising a head or top plate, abrasive material on the under side thereof adapted to engage the upper periphery of a drawing roll, a propelling mechanism mounted in pendent bearings adjacent to one edge of the said'head and a pendent guide-stop on the side of said head opposite said cone whereby the said device is held in position on the drawing roll;

after set forth and described and more particularly pointed out, in the claims hereto appended.

Referring to the drawings: Figure 1 is a mule spinning frame, showing a roll cleaner embodying the invention in position on the top of the upper drawing roll; Fig. 2 is an end view of the said drawing roll mechanism and cleaner Fig. 3 is a plan view of the bot tom of the cleaner; Fig. 4 is a side elevation thereof; Fig. 5 is an end view thereof, and Fig. 6 is a cross section on the lines 66 of Fi .131

like letters refer to like parts throughout the several views.

In the embodiment of the invention shown in the accompanying drawings, it is illustrated as applied to the top drawing roll a, of the drawing roll mechanism 12, of an ordinary and well known type of mule spinning frames. Inasmuch as the invention appertains solely to the roll cleaning device, and as the construction, arrangement and operation of the spinning mule is well known, no detailed description of the latter will be herein entered into. The said roll cleaner comprises an elongated head or top plate 0, having permanently secured on the under side thereof, near one edge, a card d, the metallic teeth d of which project downwardly. Adjoining one edge of the said card, is a side piece in the nature of a pendent guide-stop 6, preferably taking the form of a continuous strip of material fixed parallel to one edge of the head 0. This guide-stop is of sufficient depth to engage the periphery of the drawing roll below the top thereof to an extent to hold the entire cleaning device against toppling forward from the said roll a. The head or top plate 0, on the other and rear side of the said card, d, carries propelling means, preferably comprising a plurality of rotary cones f, f, the peripheries of which adjacent to the card d, are in superficial alinement with each other, and adapted to simultaneously engage the drawing roll 0. These rollers are suspended from the head or top plate 0, by means of yokes g, g, in which said cones are mounted. is preferable to employ a plurality of such cones positioned apart from each other and at widely'divergent points of the head or top plate 0, such arrangement having proven more reliable and satisfactory in use than a single cone, especially where the draft roll is made in sections of varying diameters, in which latter case the use of one cone alone might not be of sufficient length to bridge over the space between the said sections and thus be inoperative, while with the use of two cones as described, one might become inactive and the other one still be active and continue to propel the cleaner. To

with their contained cones f, f, as will permit the regulation of the pressure exerted: by the said cones upon the drawing roll, and the axial adjustment of said cones to bring the inner periphery of such into alinement as heretofore referred to, and to permit the adjustment of the yokes toward and from the card d, to vary the space between the guide-stop e and the cones to in a manner adapt or fit the cleaner to rolls of different diameters, the said yokes are provided with adjustable fastening means adapted to engage said yokes andthe head plate, consisting of screw threaded openings in said yokes adapted to respectively receive set screws h, h, passing through laterally elongated slots *5, j, in the head or top plate a, and adapted to bear upon the upper surface thereof. By means of the said screws, h, or h, either or both ends of either yoke may be adjusted as desired and locked in position.

Various expedients have heretofore been 1 the said roll a. of this frictional engagement varies with dif- 1 ferent machines, and the desired velocity or speed of travel of the cleaner.

permit such adjustment of the yokes g, g,

1 the cone.

adopted to remove the dust, dirt and sliver from the drawing roll of spinning frames, but as a rule it has been found necessary, to

,clean said rolls, to remove them from the frame and clean them by hand, with the aid of sand paper. .To avoid the delay occasioned by this practice, a device is provided wherein the cleaner itself has a durable element which will come into such intimate and 1 continuous contact with the rolls as to thoroughly clean same while in operation, the

metallic card (1, serving to thoroughly cleanse the surface of the roll by adapting itself perfectly thereto without such wear as will tend to materially diminish the life of the cleaning 1 device.

The operation of the herein described mechanism is substantially as follows:-The

Sroll cleaner device, as heretofore described,

is applied to the spinning frame by placing it directly upon the drawing roll, with the small end of the cones f, f, to the right and with the guide-stops toward the carriage.

This brings the card (i, into engagement with the top periphery of the drawing roll a, with the guide-stop e, positioned in front of the drawing roll and the cones f, f, engaging the I roll at a point thereof beyond that of the engagement of the card (1, with the said roll. When the device is so positioned the set screws h, 7i, are released and the yokes g, g,

turned in a manner to cause the cones to engage the roll a, along the entire or a part, of the periphery of the said cone in a manner to secure such frictional engagement of these parts with each other as to cause the head or 1 top plate 0, and the various elements of the device, to be fed longitudinally or axially of It is found that the extent It will be observed that the axes of the cone. The center of rotation of the cone being pitched toward that of the roll a, each point of any circumference of the" cones will 1 engage a different point of the roll, thus causing' a constant change of position of the cone relative to the roll, providing that the friction is sufficient to cause such movement of Hence a variance of the angle of the axes of the cones and the drawing roll,

will cause a proportionate increase or dimif nution of the velocity of travel of the cleaner, Q and of the friction between the cones and the roll.

The weight of the device will serve to cause the said cones f, f and the guide-stop tendency of the device to topple by reason of 1 the excess weight of the cones and their yokes, or the drag of the roll a on said cones, is avoided. The concentration of weight on the cones serves to secure the requisite frictional engagement thereof with the roll a.

The cones being positioned. beyond the card (1, relative to the direction of rotation of the roll a, the surface of the roll a engaging said cones will always be clean, thus avoiding the fouling of these elements. The said cones being spaced apart as described, are caused to simultaneously engage different sections of the drawing roll (1, thus insuring a continuous feeding movement of the cleaner.

As the drawing roll a, is rotated in paying 7 out the roving or yarn, small fibers or slivers accumulate thereon, together with dust and dirt to an extent to materially interfere with the working of the machine. the entire roll, however, is successively brought into engagement with the card 11, which, by reason of the number and character of its teeth, thoroughly scrapes off such refuse from the surface of the roll and keeps said roll perfectly clean. The said card is caused, by the cones, in the manner above described, to slowly and gradually traverse the entire length of the roll thus subjecting every part thereof to a thorough scraping and cleaning by reason of the extended area of the cleaning surface of the card. The number of teeth on the card, and the spiral course of same on the roll, due to the simultaneous longitudinal movement of the card and the rotary movement of the roll, insures the teeth engaging every part of the surface of the roller. The teeth of said card being more or less flexible give readily to accommodate themselves to the curved surface of the roller, thus securing an intimate contact with all parts thereof while they offer an abrasive surface which acts as a cleaning agent as effectively as sand paper. Wear on the teeth of said card will bring it, as an entirety, into more intimate relation with the roll thus tending rather to increase than diminish its efficiency. The particles of dust, dirt, fiber and sliver scraped from the roll a by the teeth 01, instead of being cast upon the parts of the machine below the drawing roll, are enmeshed by said teeth, from which they may be readily combed by taking the cleaner from the machine. The device having traversed the roll a as described, may be manually removed from one end of the roll and placed upon the other to repeat the operation.

We are aware of the fact that it is old in this art to provide cone propelled roll cleaners,

The surface of but it is not our intention to claim such, the invention residing more particularly in the manner of assembling the various essential parts ofthe device so as to secure high efi'1 ciency, compactness and chea ness.

It is not our intention to limit the invention to the details of construction shown in the drawings, it being apparent that such may be varied without departing from the spirit and-scope of the invention.

Having described the invention, what we claim as new and desire to have protected by Letters Patent is v 1.
